你好, 我想知道什麼是斯威夫特相當於3什麼是swift 2相當於swift 3「string contains」函數?通過npn.dev
mySong.contains
爲斯威夫特2的Xcode 7(因爲我想爲iPhone 4創建一個應用程序)。對不起,我的英語,因爲我是法國人...和谷歌翻譯幫我
我的代碼:
func gettingSongName(){
let folderURL = NSURL(fileURLWithPath: NSBundle.mainBundle().resourcePath!)
do{
let songPath = try NSFileManager.defaultManager().contentsOfDirectoryAtURL(folderURL, includingPropertiesForKeys: nil, options: .SkipsHiddenFiles)
for song in songPath{
var mySong = song.absoluteString
if mySong.contains(".mp3") { // Value of type 'String' has no member 'contains'
let findString = mySong.components(separatedBy: "/") // Value of type 'String' has no member 'components'
mySong = findString[findString.count-1]
mySong = mySong.replacingOccurrences(of: "%20", with: " ") // Value of type 'String' has no member 'replacingOccurences'
mySong = mySong.replacingOccurrences(of: "e%CC%81", with: "é") // Value of type 'String' has no member 'replacingOccurences'
mySong = mySong.replacingOccurrences(of: "e%CC%82", with: "ê") // Value of type 'String' has no member 'replacingOccurences'
mySong = mySong.replacingOccurrences(of: ".mp3", with: "") // Value of type 'String' has no member 'replacingOccurences'
songs.append(mySong)
print(mySong)
}
}
myTableView.reloadData()
}catch{
}
}
預先感謝您, npn.dev
謝謝,我會嘗試 –
